Abstract (en)
[origin: EP4063658A1] Provided is a scroll compressor capable of sufficiently supplying lubricating oil to a compression chamber located between an outermost side surface of a wrap of a fixed scroll and an inner side surface of a wrap of a movable scroll. A fixed-side end plate (24a) of a fixed scroll (24) includes a first fixed-side passage (24a5) and a second fixed-side passage (24a6). The first fixed-side passage communicates with a high-pressure space (71). The second fixed-side passage is a passage configured to supply lubricating oil from the high-pressure space to a compression chamber (40). A movable-side end plate (26a) of a movable scroll (26) includes a movable-side groove (26a2). The movable-side groove intermittently allows communication between the first fixed-side passage and the second fixed-side passage while the movable scroll turns. A first fixed-side hole (24c1) of the second fixed-side passage intermittently communicates with the movable-side groove while the movable scroll turns. A second fixed-side hole (24c2) of the second fixed-side passage intermittently communicates with a second compression chamber (40b) located inside a first compression chamber (40a) located on an outermost side, while the movable scroll turns.
